DELL WIRELESS KEYBOARD. I INSTALLED TWO BRAND NEW AA BATTERIES. COMES COMPLETE WITH THE DELL WIFI GIZMO WHICH PLUGS INTO A STANDARD USB PORT. I PLUGGED THE GIZMO INTO MY USB PORT AND MY LAPTOP READ IT AS 2.4G MOUSE, KEYBOARD AND PEN. TWO GREEN LIGHTS CAME ON.
DON'T HAVE A CLUE WHAT ALL THAT MEANS.

MY WIFE BOUGHT IT FOR HER DELL DIMENSIONS DESK TOP COMPUTER. ONE OF THE LEVELING LEGS IS BROKEN/MISSING. PROBABLY MY FAULT. UNFORTUNATELY, THAT IS ALL I CAN TELL YOU ABOUT IT. I KNOW LONGER HAVE THE DESK TOP COMPUTER AND WOULD NOT KNOW HOW TO TEST THE KEYBOARD SEPARATELY FROM THE OTHER GIZMO.
